Abstract
A satellite signal distribution system distributes signal blocks
of two different received frequencies and polarities simultaneously
over the same cable. The satellite system includes a satellite dish
or antenna that receives signals. These received signals are
transmitted to a block frequency converter that enables the
different frequency polarity blocks to be distributed
simultaneously via a single cable. The cable is coupled to a
head-out receiver processor which distributes the signals to
satellite receivers. The receivers are connected to TVs or other
sources. This unique design and configuration provides for a system
that will permit satellite broadcast signal distribution to
high-rise buildings, hospitals, condominiums, schools, and the
like.

BACKGROUND OF THE INVENTION
[0006] 1. Field of the Invention
[0007] The present invention relates generally to a satellite
broadcasting receiving and distribution system, and more
particularly to a broadcasting receiving and distribution system
that will allow for the transmission of vertical and horizontal (or
left-hand circular and right-hand circular) polarization signals
simultaneously via a single coaxial cable.
[0008] 2. Description of the Prior Art
[0009] Satellite broadcasting has become very popular throughout
the United States. Conventionally, broadcast signals are
transmitted through an artificial satellite at very high
frequencies. These frequencies are generally amplified and are
processed by a satellite receiving arrangement after being received
by an antenna or antennas, and prior to application to a
conventional home television set or the like.
[0010] The satellite receiving arrangement is generally composed of
an outdoor unit generally associated with the antenna and an indoor
unit generally associated with the television set or the like. The
outdoor and indoor units are coupled via a coaxial cable.
[0011] As an example, U.S. Pat. No. 5,301,352 issued to Nakagawa et
al. discloses a satellite broadcast receiving system. The system of
Nakagawa et al. includes a plurality of antennas which,
respectively, include a plurality of output terminals. A
change-over divider is connected to the plurality of antennas and
has a plurality of output terminals. A plurality of receivers are
attached to the change-over divider for selecting one of the
antennas. Though this system does achieve one of its objects by
providing for a simplified satellite system, it does, however,
suffer a major shortcoming. This system is silent as to any means
of simultaneously transmitting vertical and horizontal polarized
signals via a single coaxial cable.
[0012] U.S. Pat. No. 5,206,954, issued to Inoue et al. discloses
yet another satellite system that includes an outdoor unit that is
connected to a channel selector. In this embodiment, the satellite
signal receiving apparatus receives vertically and horizontally
polarized radiation signals at the site of a receiving antenna. The
signals are then transmitted, selectively to provide for either one
of the vertically or horizontally polarized signals to be
transmitted. This design and configuration provides for one coaxial
cable to be utilized, but does not provide for the vertical and
horizontal signals to be transmitted simultaneously, but rather,
selectively.
[0013] None of these previous efforts, however, provide the
benefits intended with the present invention. Additionally, prior
techniques do not suggest the present inventive combination of
component elements as disclosed and claimed herein. The present
invention achieves its intended purposes, objectives and advantages
over the prior art device through a new, useful and unobvious
combination of component elements, which is simple to use, with the
utilization of a minimum number of functioning parts, at a
reasonable cost to manufacture, assemble, test and by employing
only readily available material.
SUMMARY OF THE INVENTION
[0014] The illustrative embodiment of the present invention
provides a satellite broadcast receiving and distribution system
that will permit for the transmission of vertical and horizontal
(or left-hand circular and right-hand circular) polarization
signals simultaneously via a single coaxial cable. The system will
accommodate two different polarity commands from two or more
different sources at the same time. This exemplary satellite
broadcast receiving and distribution system will provide for the
signals received from the satellite to be converted to frequencies
which the line amplifiers can transport. This will permit the
signals to travel via existing wiring in buildings, high-rises,
hospitals, and the like so that satellite broadcasting can be
viewed by numerous individuals by way of a single satellite
antenna.
[0015] The exemplary satellite broadcast system consists of a
satellite antenna which receives the polarized signals. These
polarized signals are transmitted to a head-in processor and are
converted to different frequencies in order to render the different
signals to be transmitted simultaneously. Hence, the head-in
processor will permit for the transmission of signals of two
different frequencies and polarities to be transmitted
simultaneously, and will also accommodate two different polarity
commands from two or more different television receivers at the
same time via a single cable. This cable is coupled to a head-out
processor. These signals, once in the head-out processor, will be
converted to frequencies that are required for the source (i.e.
television). Once converted, the signals are transmitted to a
satellite receiver. This satellite receiver is coupled to the
source.
[0016] Accordingly, it is the object of the present invention to
provide for a satellite broadcast receiving and distribution system
that will convert different frequencies and different polarized
signals in order to permit the signals to be transmitted via a
single cable.
[0017] It is another object of the present invention to provide for
a satellite broadcast receiving and distribution system that will
provide service to mid/high-rise office buildings, condominiums,
schools, hospitals and the like via a single cable.
[0018] A further object of the present invention, to be
specifically enumerated herein, is to provide a satellite broadcast
receiving and distribution system in accordance with the preceding
objects and which will conform to conventional forms of
manufacture, be of simple construction and easy to use so as to
provide a system that would be economically feasible, long lasting
and relatively trouble free in operation.
[0019] The present invention meets the requirements of the
simplified design, compact size, low initial cost, low operating
cost, ease of installation and maintainability, and minimal amount
of training to successfully employ the invention.
[0020] An example embodiment of the present invention provides a
satellite broadcasting system comprising a satellite dish coupled
to a low-noise block converter. The low-noise block converter is
coupled to a first means of converting vertical polarization
signals and horizontal polarization signals (or left-hand circular
polarization signals and right-hand circular polarization signals)
from a satellite, and transmitting both polarity signals
simultaneously via a single coaxial cable. This enables two
different frequencies and polarities to be transmitted
simultaneously via a single coaxial cable.
[0021] The example embodiment further includes a second means
coupled to the first means. The second means converts the vertical
polarization signals and the horizontal polarization signals (or
said left-hand circular polarization signals and the right-hand
circular polarization signals) from the first means to frequencies
for a source. A satellite receiver is coupled to the second means.
The source is coupled to the satellite receiver.
[0022] The example embodiment further includes a power source
coupled to the first means. The power source powers the first
means.
[0023] In accordance with a further aspect of the preferred
embodiment, the second means provides for the signals to be
converted separately and independently to the satellite receiver by
a transmitting means. The present invention in one of its aspects
further provides a transmitting means for the signals to be
selectively converted to the satellite receiver via a first cable
coupled to the second means.
[0024] In accordance with a further aspect of the invention, the
transmitting means further includes a polarity switch for
permitting the signals to be selectively converted to the satellite
receiver.
[0025] In accordance with a still further aspect of the invention,
the first means includes a first converting system for converting
the signals of a first direction to a desired first frequency and
polarization, and a second converting system for converting the
signals of a second direction to a desired second frequency and
polarization. The first converting system may include a first down
converter which is coupled to an amplifier. The second converting
system may include an up converter coupled to a second down
converter. A joining means may be coupled to the amplifier and the
second down converter. The joining means may include a four way
splitter. A phase lock loop transmitter may be coupled to the four
way splitter.
[0026] In accordance with a further aspect of the invention, the
second means includes a splitting means to split and divide the
signals from the single coaxial cable to enable the signals to be
transmitted to a first converting system and a second converting
system. The first converting system may convert the signals of a
first direction to a desired first frequency and polarization for
the satellite receiver. The second converting system may convert
the signals of a second direction to a desired second frequency and
polarization for the satellite receiver. The first converting
system may include a first up converter which is coupled to a
splitting means and a first down converter which is coupled to a
first down converter. The first down converter may be coupled to
the satellite receiver via a first line. The second converting
system may include a second up converter coupled to the splitting
means. The second up converter may be coupled to the satellite
receiver via a second line. The splitting means may include a four
way splitter. A phase lock loop may be coupled to the four way
splitter.
[0027] In accordance with a further aspect of the invention, a
first converting system includes a first up converter which is
coupled to a splitting means and to a first down converter. The
first down converter may be coupled to a joining means. The second
converting system may include a second up converter coupled to the
splitting means and to the joining means. A polarity switch may be
coupled to the first down converter and the second up converter.
The polarity switch may be coupled to a first cable which is
coupled to the satellite receiver.
[0028] In accordance with a further aspect of the invention, the
splitting means and the joining means each include a four way
splitter, and a phase lock loop receiver is coupled to the spitting
means. The splitting means may split and divide signals from the
single coaxial cable to enable said signal to be transmitted to a
third converting system for converting the signals of said first
direction and a fourth converting system for converting the signals
of the second direction.
[0029] The third converting system includes a second up converter
which is coupled to the splitting means and to a third down
converter. The third down converter may be coupled to the satellite
receiver via a first conduit. The fourth converting system may
include a third up converter coupled to the splitting means. The
third up converter is also coupled to the satellite receiver via a
second conduit.
[0030] The foregoing has outlined some of the more pertinent
objects of the invention. These objects should be construed to be
merely illustrative of some of the more prominent features and
application of the intended invention. Many other beneficial
results can be obtained by applying the disclosed invention in a
different manner or modifying the invention within the scope of the
disclosure. Accordingly, a fuller understanding of the invention
may be had by referring to the detailed description of the
preferred embodiments, in addition to the scope of the invention
defined by the claims taken in conjunction with the accompanying
drawings.
BRIEF DESCRIPTION OF THE DRAWING
[0031] FIG. 1 illustrates a block diagram representing the
satellite broadcast signal receiving and distribution system
according to a preferred non-limiting exemplary embodiment of the
present invention.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0032] As illustrated in FIG. 1, the satellite system of a
non-limiting preferred example embodiment of the present invention
includes a receiving satellite antenna 1 that is connected to a
head-in equipment frequency processor 44. It is at this head-in
equipment frequency processor 44 where the signals
(Vertical-polarized signals and Horizontal-polarized signals; or
left-hand circular and right-hand circular polarization signals)
are received simultaneously and then transmitted via a single
coaxial cable 13 to the head-out receiver processor 45 or 46. From
the receiver processor 45 or 46, the signals are transported to a
satellite receiver 27 or 41 and to a source 29 or 43 (this figure
illustrates a television as its source).
[0033] As illustrated, the receiving satellite antenna 1 is
connected to a low-noise block converter (LNB) 2 for amplifying and
converting the respective polarized signals (Vertical-polarized
signals and Horizontal-polarized signals; or left-hand circular and
right-hand circular polarization signals). This LNB converter 2 is
coupled to the head-in equipment frequency processor 44.
Accordingly, after signals are received, they pass the low-noise
block converter 2, to provide for the signals to enter the head-in
equipment frequency processor 44 (illustrated in dashed lines) via
lines 3 and 4.
[0034] The head-in equipment frequency processor 44 provides for
the signals via lines 3 and 4 to be converted to the frequencies
which the line amplifiers can transport via converters 5 and 7,
respectively. From the lines 3 and 4, the signals or transponders
are transmitted to a first converter or down converter 5 and a
second converter or up converter 7, respectively. These frequency
converters convert the entered frequencies to frequencies which the
line amplifiers can transport.
[0035] The utilization of two converters permits for the acceptance
of two signals or polarized transponders that are of a different
frequency.
[0036] In the down converter 5, the transponders are converted down
to a specified frequency. This specified frequency is the frequency
that is required for the line amplifiers to transport. The newly
converted frequencies are amplified through the amplifying means 6.
At means 6, the converted frequencies are amplified so as not to
create second harmonics. These signals are then transferred to a
four way splitter 10.
[0037] In the up converter 7, the transponders are converted up to
a specified frequency. The converted frequencies then are converted
down via down converter 8. This process of converting up and then
down provides for frequencies to be converted without difficulties
and avoiding any forbidden conversion area.
[0038] The converted signals are transferred to the four way
splitter 10 in order to combine the frequency output of the
amplified signal of amplifier 6 and the frequency output from
converter 8. To synchronize the system, the frequencies from the
phase lock loop (PLL) 9 are transmitted to the splitter 10.
[0039] From splitter 10, the signals are passed through an A.C.
power separator 11. Block 12 routes 60 Volts power to a D.C. power
supply of 18 Volts.
[0040] This will permit for the dual polarization frequency blocks
from the satellite dish 1 to be transmitted simultaneously via a
single coaxial cable 13. Dependent upon the length of the cable, an
optional amplifier 14 can be coupled thereto. Power from a power
source 16 is inserted into the lines via a power inserter 15. The
signals are amplified, as needed, with an additional amplifier(s)
17. It is noted that the amplifiers are optional and are dependent
to the distance that the head-in frequency processor 44 is located
from the head-out receiver processor 45 or 46. The power supply and
power source 12 energizes the head-in frequency processor 44.
[0041] From the single coaxial cable 13, the signals are adjusted
via a tap 18 or 31 to permit for the appropriate power level
(decibels) that is required for the head-out receiver processor 45
or 46.
[0042] The head-out frequency processor 45 can take the form of a
plurality of embodiments. The design and configuration of the
head-out frequency processor 45 is dependent on the source (e.g.,
TV 29) in combination with the satellite receiver 27.
[0043] The first embodiment for the head-out receiver processor is
illustrated in FIG. 1 and is represented by way of dashed lines 45.
As seen in this head-out receiver processor 45, the simultaneously
transmitted signals enter the processor 45 via line 19. The line 19
is coupled to a four (4) way splitter 20. A phase locked loop (PLL)
receiver 21 is coupled to the splitter 20 to permit for the signals
to be locked to the proper and desired frequencies. From the
splitter, the first frequency is transmitted to a first converter
22 in order to permit signals or transponders to be converted up to
a specified frequency. This up converted signal is then transmitted
to the satellite receiver 27 by way of a line 26.
[0044] The second frequencies are transmitted to a first or up
converter 23 and then is transmitted to a second or down converter
24. This will permit for the signals to be converted to the desired
frequency. The conversion of the signals from up to down provides
the benefit of converting the frequencies without any mishap or
error. This method of conversion will avoid the forbidden
conversion area. This second or down converter 24 is coupled to the
satellite receiver 27 via line 25. The signals received from the
satellite 1 can then be transmitted to the TV (source) 29 by line
28.
[0045] As illustrated, this head-out receiver processor 45 is the
reverse process of the head-in processor 44. This is to provide for
the signals to reconvert to their original frequencies so as to
provide for the satellite receiver and TV (source) to accept the
signals. The single cable 13 accepts the signals at frequencies
different than that of the TV (source) 29 and satellite receiver
27. Accordingly the head-out receiver processor 45 must reconvert
the signals to the frequencies that are utilized by the TV (source)
29 and satellite receiver 27. This design and configuration of the
head-out receiver processor is dependent on the design and
configuration of the satellite receiver 27.
[0046] An alteration of the satellite receiver 27 requires an
alteration in the head-out receiver processor. This alteration is
illustrated in FIG. 1 and is shown in outline and designated as
reference 46. In this design and configuration, the satellite
receiver 41 utilizes only one wire 40 and accepts only one type of
signals at a time, such as left-hand circular polarized signals or
right-hand circular polarized signals.
[0047] As seen, the frequencies are tapped via 31. The tap 31 is
coupled to the head-out receiver processor 46 via line 32 which is
connected to a four (4) way splitter 33. To provide for the signals
to be locked in proper frequencies, the four way splitter 33 is
coupled to a phase locked loop (PLL) receiver 34.
[0048] From the splitter 33, the first signal is transmitted to a
first or up converter 36, and then is transmitted to a second or
down converter 37. The conversion of the signals from up to down
provides the benefit of converting the frequencies without any
mishap or error. This method of conversion will avoid the forbidden
conversion area.
[0049] The signals from the splitter 33 are transmitted to an up
converter 35 which will inherently convert the signals.
[0050] A polarity switch 39 is connected to converters 35, 36, 37
in order to permit for the head-out receiver processor to be
coupled to the satellite receiver 41 via a single cable 40 and a
joining means 38 which is a four (4) way splitter. The satellite
receiver 41 is connected by way of line 42 to a TV (source) 43.
[0051] It is noted that FIG. 1 illustrates the use of two head-out
receiver processors, but in actuality, only one head-out receiver
processor need be utilized with the head-in processor 44. The type
and embodiment for the head-out receiver processor is dependent on
the combination of the satellite receiver and TV (source) that are
utilized.
[0052] The satellite system of the present invention will permit
for two signals of different frequency and derived from different
polarities to travel simultaneously via a single coaxial cable. The
use of this satellite system will provide for a satellite system
that is versatile, economical, and compact. The usage of the single
cable permits for a system that can accept satellite broadcasting
in places that were previously rendered impossible. These places
includes mid/high-rise office buildings, condominiums, hospitals,
schools, etc. The unique design and configuration enables the
signals to be transmitted via the existing wiring of the buildings.
The only renovations that may need to be done is the upgrading of
the existing amplifiers.
[0053] While the invention has been particularly shown and
described with reference to an embodiment thereof, it will be
understood by those skilled in the art that various changes in form
and detail may be made without departing from the spirit and scope
of the invention.
